Hi Deepaji,
Your chart based on Dasa transit and KP Astrology shows 70% chance of marriage happening in Mercury-Moon Dasa before June end and since you believe in power of prayer, I would suggest remedies including Fasting on Thursday if possible uttering Guru beeja mantra. .But if you are already continuing Monday fast, then I would not suggest fasting one more day.Do you think you can recite Swayamvara Parvathi mantra Japa which I have found has helped in number of my cases? This would overall strengthen your position.I respect your views and would definitely not like to impose on your views in this regard.
But please do remember to match the horoscope of your prospective Spouse with that of yours.
Cheer up.Dont lose heart.Everything happens for good for God loving persons.
God bless
Ray
